CC -!- FUNCTION: One of the components of the high-affinity ATP-driven
CC potassium transport (or KDP) system, which catalyzes the
CC hydrolysis of ATP coupled with the exchange of hydrogen and
CC potassium ions (By similarity).
CC -!- CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate +
CC K(+)(In).
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein
CC (By similarity).
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type)
CC (TC 3.A.3) family. Type IA subfamily.
